Morgan Stanley made an error analysing Snapchat, and it shines a light on some big flaws in Wall Street research

On March 27, Morgan Stanley published an equity research note on Snap, the social media company it helped take public, putting a $US28 price target on the stock.

Almost a day later, the bank issued a correction, changing a range of important metrics in its financial model but not the $US28 price target.

That has some on Wall Street raising doubts about the research and equity research more broadly.

Imagine the following scenario.

A Wall Street investment bank has just led the biggest tech initial public offering in years but makes a mistake in the first research note it publishes on the stock.

The error means the bank overstated the forecasted earnings over a five-year stretch by nearly $US5 billion. Yet when the bank issues a correction and updates its earnings models, its price target on the shares remains the same.

How does that happen?

The answer says a lot about the weaknesses in Wall Street analyst research and the closely watched price targets published by big banks. Those numbers can move markets and underpin the Street’s buy or sell recommendations on the shares. But they’re also dependent on highly subjective calls by the research analysts, which often are themselves worth scrutinizing.

The bank in question is Morgan Stanley, and the company is Snap. Morgan Stanley led Snap’s IPO, a $US3.4 billion share sale deemed a huge success by Wall Street standards.

On March 27, nearly a month after the stock debuted, the bank published its first research note on shares of the newly public social media company, slapping a $US28 price target on them. That’s 23% above where the shares ended trading the week before, and the bank’s advice to clients was to buy.

The note, written by Brian Nowak and his team, was a part of a flood of positive analyst commentary on the company, much of it from the investment banks that worked on the offering. The shares, which by then had lost some of their post-IPO glow, popped on the bullish sentiment.

About 22 hours later, Morgan Stanley issued a second note that on the first read looked nearly identical. But the new note lowered estimates for Snap’s future earnings and included several other changes in the analysis.

Toward the bottom of the second page, in italics, the analysts wrote:

“We have corrected a tax calculation error in our model that overstated adjusted EBITDA in 2021-2025. We have updated the text and charts in the following note to reflect our estimate changes. Note that our revenue forecast and fundamental top-line drivers (DAUs, ad load, etc.) remain unchanged.”

One other thing that didn’t change, despite some significant adjustments to the financial model Morgan Stanley published? That $US28-a-share price target.

Future earnings estimates are often a key determinant of an analyst’s estimate of a company’s current value. A lower earnings estimate, then, ought to lead to a revision in the price target, even by a small amount. It didn’t work that way in Snap’s case because Morgan Stanley also corrected some other assumptions in its model — changes that left the model out of sync with those used by others on Wall Street.

“It almost feels that they’re backing into the numbers,” said Charles Lee, a professor at the Stanford Graduate School of Business. “It just so happens that the two work out so that they don’t have to change their price target.

“It’s almost humorous,” Lee added. “And, of course, it can be totally innocuous, and it just so happens they found two offsetting errors, and that’s their opinion, and the price target should be unchanged. One has to sort of chuckle because there seems to be so much play in the numbers that they could have put anything in.”

It’s true analysts make many assumptions that may or may not prove accurate, but that they were changed with no material effect on the conclusion makes them unreliable, according to some.

“If the price target can be manipulated so easily, then they are not valuable and likely should not be relied upon,” Lee Bressler, a portfolio manager at the hedge fund Carbon Investment Partners, told Business Insider.

How it happened

In the first note, Morgan Stanley said it saw “companywide adjusted EBITDA margins reaching 40% by 2025.” In the second note, it said it expected margins to hit 30% by 2025.

Similarly, financial models had to be updated. Here’s the model for discounted cash flow from the first note, with a breakdown of adjusted EBITDA for 2015 through 2025. Morgan Stanley put Snap’s expected adjusted EBITDA at $US6.57 billion and free cash flow at $US4.05 billion in 2025.

Here’s the second, with the revision to the expected adjusted EBITDA. In the updated note, Morgan Stanley forecast adjusted EBITDA to be $US4.92 billion in 2025.

In other words, the revisions to the model cut Snap’s 2025 adjusted EBITDA by about $US1.7 billion. Free cash flow dropped to $US2.42 billion, a decrease of $US1.6 billion.

Despite those changed calculations, the price target did not change because Morgan Stanley also updated a range of other metrics. In the same italicized section of the updated research report, Morgan Stanley said:

“We have also corrected our discounted cash flow calculation so that it is consistent and comparable across our US internet coverage. More specifically, we are lowering our SNAP equity risk premium from 5.59% (an estimated pre-IPO rate) to 4.29% (consistent with other companies in our group). This change lowers our WACC to 8% (from 10%). On an aggregate basis, our price target is unchanged at $US28/share.”

What is WACC?

WACC is the weighted average cost of capital, a measure that takes into account the cost to a company of issuing equity and borrowing. It is one of many highly subjective numbers that analysts plug into their models.

In the model for discounted cash flow that Morgan Stanley used to value the company, WACC is used to adjust the value of future cash flows. The higher the WACC, the higher the discount applied to future cash flow and the lower the value of those future cash flows. A higher WACC would lower the value of the company.

The flip side is that when you lower the WACC, you raise the equity value.

In the original research report, Morgan Stanley put Snap’s WACC at 9.7%. In the second report, Morgan Stanley lowered the WACC to 8%.

The effect? The negative effect of having to correct adjusted EBITDA was canceled out by the positive effect of correcting the WACC.

Morgan Stanley included a table in the second report showing the effect of changes in the WACC to the equity value. With a WACC of 8% and a long-term growth rate of 3.5%, Snap had an estimated equity value of $US39.6 billion.

With a WACC of 9%, lower than Morgan Stanley’s 9.7% original estimate, Snap’s equity value would drop to $US31.2 billion. That would mean a much lower price target than $US28 per share.

Morgan Stanley

Morgan Stanley’s changed assumptions about Snap’s WACC are in line with the figures it uses in research on other internet companies that have been public for some time.

For example, it lowered the WACC for Priceline in January to 8% from 10%, and it made a similar move with Expedia, lowering it to 7% from 9%.

It uses a WACC of 8% for Alphabet and Etsy and a 7.7% WACC for Amazon. It uses a 9% WACC for Facebook.

Still, the change put Morgan Stanley out of sync with its peers on Wall Street. Not every bank that worked the deal included a WACC in its research. However, most of those that did used a WACC significantly above the 9.7% and 8% figures that Morgan Stanley used.

Here are some of the relevant estimates from banks that worked on the deal:

Credit Suisse: “We have used a weighted average cost of capital of 11% and a terminal growth rate of 3%.”

Deutsche Bank: “We use a WACC of ~16% in our DCF which assumes no debt in the capital structure.”

RBC Capital Markets: “Our $US31 price target is also supported by a DCF, based on an 11% WACC and a 5% long-term growth rate.”

Atlantic Equities, a bank that wasn’t on the Snap deal, used an 11% WACC in its model.

It also means that Facebook, a $US410 billion company that generated $US10.2 billion in net income in 2016, has a higher WACC than Snap, a $US26 billion company that hasn’t yet turned a profit. One investor took issue with that, saying Snap should have a higher cost of equity than Facebook.

Morgan Stanley’s $US28 price target is on par with that of many of its peers, though. Goldman Sachs had a target of $US27, Credit Suisse $US30, and RBC Capital Markets $US31.

Still, Morgan Stanley’s changes to its assumptions that didn’t change Snap’s price target raise questions about the right valuation for Snap. It also raises important questions about the value of these models, especially when it comes from a bank that has an interest in the success of the IPO, Lee said.

“If you’re an investor, anybody who really cares about the long-run value of this bet, you probably want to discount this [report] more than the others, given their affiliation” as IPO underwriter, he said.
